以地下水作为供水水源的水厂,在工艺流程上较地面水简单,故地下水水厂节能的重点应放在技术管理、管网布置、深井泵的管理、变配电系统的布置上。一、不设水塔、或设对置水塔对节电有利 1.水塔是一个地方的供水最高点,有的水厂把水塔设在泵房旁边(网前水塔)高一般为30米左右,由于输水管道的距离远,管网布置不合理(特别是枝状管网),造成管网终点的服务水头不足。特别是高峰供水时矛盾更突出。原因是水塔设在泵房旁边,供水压力一定,在管网延伸后压力不足,另一方面,水泵杨程受水塔控制,多余的杨程白白浪费掉。又由于管网布置不够理想,水头损失较大,造成供水压力不足而电耗过大的反常现象。故可能的
Water plants that use groundwater as a source of water supply are simpler than surface water in the process flow. Therefore, the focus of energy conservation in groundwater plants should be on technical management, pipe network layout, management of deep well pumps, and distribution of the power distribution system. 1. No water towers or opposed water towers are beneficial for energy conservation 1. The water tower is the highest point of water supply in a locality. Some water plants set the water tower next to the pumping station (net tower). The height is generally about 30 meters. The distance of the water pipeline is far away, and the layout of the pipe network is irrational (especially the branch pipe network), resulting in insufficient water head for the end of the pipe network. In particular, the contradiction between the peak water supply is more prominent. The reason is that the water tower is located next to the pump room, the water supply pressure is certain, and the pressure is insufficient after the pipe network is extended. On the other hand, the pump Yang Cheng is controlled by the water tower, and the excess Yang Cheng is wasted. Moreover, due to the unsatisfactory layout of the pipe network, the loss of the water head is large, resulting in an anomaly in which the pressure of the water supply is insufficient and the electricity consumption is excessive. It is possible
